I applied online. The process took 3 weeks. I interviewed at Zalando (Berlin) in Sept 2015
Interview
Technical phone interview with general questions on my background and career goals. Nice conversation. Boilerplate message from HR director inviting me to not take "today’s outcome as a negative comment about your abilities or personality"...
Interview questions [2]
Question 1
Prime number pairs (eg, 5-7, 11-13): why is the number in between dividable by 6?
